Cullen Jewellery’s Modern Take on Lab-Grown Engagement Rings
Lab-grown diamonds are having a major moment, and for good reason. As more couples prioritise sustainability and responsible sourcing, lab-grown diamonds can offer all the beauty and brilliance of their mined counterparts—without some of the environmental concerns.
Cullen Jewellery was ahead of the curve, recognising the shift before it became mainstream. Founded in 2018, the brand has established itself as a leader in high-quality, boutique lab-grown engagement rings, offering couples a conscious lab-grown choice without compromising on luxury.
It all started with a real-life love story—founder Jordan Cullen’s search for the perfect engagement ring for his now-wife. Fast-forward to today, and over 10,000 couples worldwide have chosen Cullen Jewellery for their engagement rings, wedding bands, and fine jewellery. And now, with their stunning new boutique studio on Auckland’s High Street, New Zealand couples can experience their craftsmanship firsthand.
Lab-Grown Diamonds: What You Need to Know
We recently sat down with the team at Cullen Jewellery in their latest showroom in Auckland to chat about engagement rings and the rise of lab-grown diamonds. While they’re becoming more widely known, many people still have questions about what sets them apart—and who better to clarify than Cullen Jewellery?
So, what exactly is a lab-grown diamond?
In short? It’s a real diamond. Lab-grown diamonds are made of pure carbon, just like mined diamonds, and are graded using the same four Cs—cut, colour, clarity, and carat weight. They have the same brilliance, fire, and durability, making them just as scratch-resistant and perfect for everyday wear.
What’s the key difference between a lab-grown and a mined diamond?
Aside from being a more sustainable and responsible choice, lab-grown diamonds deliver the opportunity for clients to access high-quality diamonds within budget. So, if you buy from the right supplier, you can get the stone of your dreams with less of the ethical dilemmas or the financial strain.
But, just like mined diamonds, quality varies—which is why choosing the right jeweller matters. Every one of Cullen Jewellery’s diamonds is graded by either GIA or IGI and is certified carbon-neutral by Clear Neutral, meaning their stones are both responsibly sourced and of the highest quality. With years of experience in the field, Cullen truly understand what makes an exceptional lab-grown diamond and exactly where to find it.
The Beauty of Choice: Cullen Jewellery’s Engagement Ring Collection
Choosing an engagement ring is as much about how it feels on your hand as how it looks in a box. Cullen Jewellery offers a stunning collection of ready-to-wear engagement rings, allowing you to try on different stone shapes, settings, and metals—from classic yellow gold to sleek platinum—to see what suits you best.
Many people don’t realise that ring styles can look completely different depending on hand shape, finger proportions, and skin tone—much like finding the perfect wedding dress. Some designs will naturally suit you better than others, so just like sourcing the perfect gown, trying different ring options can ensure you find the perfect match, for you.
And if you don’t find exactly what you’re looking for, don’t panic. Cullen Jewellery’s Melbourne-based jewellery team specialises in custom creations, working closely with couples to design and handcraft one-of-a-kind engagement rings that are as unique as their love story.
Bespoke design isn’t just something Cullen offers—it’s at the heart of what they do. Their team is passionate about bringing dream rings to life, whether fine-tuning an existing design or crafting something entirely from scratch. From the initial sketches to selecting the perfect diamond and refining every last detail, their expert team collaborate with you at every step to ensure the final piece is nothing short of perfect.
For Cullen Jewellery, the bespoke process is more than just craftsmanship—it’s about creating something deeply personal that reflects the love and individuality of each couple. Because your love story is one of a kind—so your ring should be, too.
A Lifetime of Craftsmanship
An engagement ring is more than a piece of jewellery—it’s a lifelong symbol of love. Every Cullen Jewellery piece comes with a Lifetime Warranty and Free Resizing, meaning your ring is designed to last as long as your love story.
And in true Cullen Jewellery fashion, their commitment extends beyond their designs. For every order placed, they plant a tree, adding an extra layer of meaning to every purchase.
